||v|PRovEM ENT IN PLows.

Specification forming part of Letters Patent No. 57,341, dated August2l, 1866.

To all whom 'it may concern:

Be it known that I, Z. VJLEE, of Blakely, in the county of Early andState of Georgia, have invented a new and useful Improvement in Plows,and I do hereby declare the following to be a full, clear, and exactdescription ot' the nature, construction, and operation of the same,reference being had to the accompanying` drawings, which are made a partof this specification, and in which- Figure 1 is a plan, and Fig. 2 is aside elevation, of a plow illustrating mv invention.

Similar letters ot' reference indicate corresponding parts in the twofigures.

My invention consists in novel devices for attaching the plow-shanks tothe beam and for adjusting the same in order to vary the workingposition of the plows.

In the ensuingdescription these devices are described in connection witha plow; but they are applicable to cultivators, as the shovelshanks ofthe latter require a similar adjustment to those of a plow.

The following description will enable others skilled-in the art to whichmy said invention appertains to fully understand and use the same.

In the accompanying drawings, A may represent the beam, B B the handles,which are bolted to the beam, and G the upright post, which joins therear end of the beam to the transverse bar D, which connects the handlestogether'.

E E E represent the plow-Shanks, which consist each of a single bar bentin the form of a U, so as to have two parallel sides with an interveningspace. The plows are designed to be attached to these shanks after themanner described in a paten t granted E. D; and Z. W. Lee on the 4th dayof October, 1859.

The upper end of each of the shanksE embraces a bracket, F, which isfastened to the beam A by means of the shackles Gr and wedges H.The-shank E is pivoted to the bracket F by a bolt or pivot, I.

J represents an arm, pivoted to the shank E at the joint e, which isbelow the point at which the shank is attached to the bracket F. Theupper edge of the arm J is formed with a small lin or projection, j,which, by engaging with the serrations on the under side of the bracketF, serve to stay the arm J in any -position to which it may be adjustedtoward the front or rear, such adj ustment being effected by means ot'the shackle K and wedge L, which hold the arm J snugly up against theunder side of the bracket, as represented. By thus adjusting the arm Jtoward the front or rear the inclination of the plow-shank E may bevaried to any desired extent, and since the plows are made to workdeeper or shallower in the soil, as occasion may require.

Any number of shanks maybe attached to the beam in the manner abovedescribed, and their number as well as their relative position is variedto suit the different varieties ot' plowing or cultivating.

The central shank, E', is attached by means of a pivot, M, and braced bymeans of the bar N,which is adjustable on the beam A; but as this formsno part of the present invention it need not be further alluded to.

Having thus described my invention, the following is what l claim as newand desire to secure by Letters Patent:

The combination of the shank E, bracket F, pivoted arm J, shackle K, andwedge L, all

arranged and operating substantially as and for the purposes hereinexplained.
